BALING- PRESS.

SPECIFICATION forming part of Letters Patent No. 376,461, dated January 17, 1888.

Application filed April 29, 1887.

To all whom it may concern: 7

Be it known that I, BENJAMIN J. WILsoN, a subject of Her Majesty the Queen of Great Britain, residing at Atlanta, in the county of Fulton and State of Georgia, have invented a new and useful Baling- Press; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to balingpresses, and is especially applicable to the class of presses that are used for repressing cotton, and which are commonly known as cotton compress ors, but this device is applicable to presses for other purposes.

Figure I is a side elevation of a portion of the press, illustrating the method of connecting the operative parts with the frame. Fig. II is also a side. elevation showing the whole gle casting.

For the purpose of illustrating the inven tion, the parts shown in the accompanying drawings are the upper portion of the-frame, the steamcylinder, the beam and platen, and the connecting-rods of a cotton-compressor, in connectionwith which I show the rolling fulcrums and their actuating-toggles and the piston-rod of a steam-cylinder, through which motion is communicated from the steam-cylinder to the toggle.

In the drawings like reference-letters mark duplicated parts in the figures.

A is the frame, and B the downwardly-facing bed, against which the cotton is pressed.

0 is the upwardly-facing movable'plat-en, between which and the bed B the cotton-bales are compressed. The bed, the platen, and all of the movable parts of the press are shown in the position in which they are previously to the compression of the bale, which is shown between the bed and the platen, and is marked D.

The-baleof cotton shown represents-a bale of cotton as ordinarily sold by the producers, andwhich is ordinarily from three to four feetin thickness, and which, for convenience of transportation, it is desirable to compress to about Serial No. 237,376. (No model.)

one-eighth its original thickness, the ties or bands being taken off and replaced by those more suited to its size, and generally more in number, in order to have sufficient holding capacity to withstand the increased tension. To accomplish this compression requires an initial force approximately estimated at from ten to twenty tons, and to bring the bale to its required thickness an ultimate pressure of about twenty'five hundred tons, which pressure must be maintained for a sufficient length of time to permit the tying of the bale by means of the tiesor bands hereinbefore referred to. To furnish a pressure that will overcome this rapidly-increasing resistance without furnishing any unnecessary excess of power during any other part of the process, I attach the pitmen E, which are pivoted at their bottoms to the platen G and at their tops to the wrists f on the rolling fulcrums F. Of

these pitmen there are four-two on the side shown and two on the opposite side, the press being in this and in all other respects alike on both sides. On the rolling fulcrums I also pivot the outer ends of the toggle-levers G, preferably by the pin f. The inner ends of the toggle-levers G are pivoted to the crosshead Hon the piston-rod K, the slides of which run in guide h. The rod K receives a reciprocating motion from the pressure of steam on the piston in the steam-cylinder M. The upward movement of the piston carries with it the cross-head H and the innercnds of the toggle-levers G, the line of pressure of the toggles nearly coinciding with the line of motion of the pivotal point f, raising the platen O with a velocity nearly equaling at the start, and consequently with a force but little, if any, greater than, that of the piston, which will be of such a size as will, with the desired steampressure, furnish a force equal to the initial pressure required. The continued upward movement of the piston continues to straighten the toggles and carry the rolling fulcrums upwardly and outwardly until the toggle-levers are horizontal, or their inner and outer pivotal points in line, thus carrying the rolling fulcrums to a vertical position, or until a line between the pivotal centers of the pitmen coincides with the pivotal center of the rolling fulcrums, which will determine the upward limit to which the platen can be carried.

The pitmcn, rolling fulcrums, and togglelevers should be of such relative lengths as will decrease the speed of the platen Gin comparison with that of the piston in an inverse ratio to that of the increasing resistance of the bale of cotton that is undergoing the process of compression, which will cause the work to be done by the cylinder to be u niform throughout its upward stroke.

As this class of compressors-that is to say, those that are directly connected to the piston of astcam-cylinderhavc been heretofore constructed, the decrease of the relative speed of the platen to the piston has not been so much as to furnish a sufficient ultimate pressure of the platen without having the cylinder much larger than is necessary for the furnishing of the initial pressure, which causes a wasteful use of the steam, which waste is entirely ohviated by my invention.

I am aware that it is not new to construct a press operated by the action of steam in a cylinder through the agency of toggle-levers eonneeted with the steam-piston moving in said cylinder, the lever being in turn connected with the moving platen of the press, and do not, therefore, broadly claim such a construction.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

In a baling-press, the frame A, having bed 13 cast integral therewith, in combination with the power-cylinder M, mounted upon the top of said frame, the cross-head H, piston-rod K, links G, fulerums F, connecting-rods E, and the movable platen O, substantially as set forth.

In testimony whereof Iafiix my signature in presence of two witnesses.

BENJAMIN J. WILSON.
